A mountain rescue operation in Snowdonia has been completed using grid refrence markers placed on posts.
The Aberdyfi Search and Rescue Team credited the refrence points as playing a key role in helping to locate a group of climbers who got lost after setting out to ascend Cadair Idris.
With the weather deteriorating, the three walkers found themselves unable to find their way and very cold, as they had set out without any Ordnance Survey Maps
and did not have the appropariate walking jackets
and other clothing needed.
Thankfully, they found one of the posts with a marker on it and were therefore able to tell the rescuers where they were.
A spokesperson for the rescue team said: "The group were poorly equipped and did not have a map, although luckily for them they had located one of the new Snowdonia National Park Grid Reference markers on a stile, which is part of the parks mountain safety initiative."
The team member reminded walkers they need to "ensure they are properly equipped and have the skills to navigate in the terrain".
Such markers have been placed in other parts of the national park and can be very useful when people do locate them, but are no substitute for maps.
With such navigational aids plus compasses and the knowledge of how to use them, walkers can avoid getting lost in the first instance.
At the same time, the importance of having the right clothing and good walking boots
cannot be understated at any time and is even more important as summer turns to autumn.
Torches will also become vital items to take as the days get shorter, particularly when the clocks go back just over a month from now.
At a height of 2,930 ft (893 m), Cadair Idris is the highest peak in Wales south of the Snowdon Horseshoe.
